DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the present embodiments of theinvention, examples of which are illustrated in the accompanyingdrawings. Wherever possible, the same reference numbers are used in thedrawings and the description to refer to the same or like parts.

FIGS. 2A and 2B are front and back views of a handheld electronic device200 according to a first embodiment of the present invention. As shownin FIGS. 2A and 2B, the handheld electronic device 200 mainly comprisesa first casing 210 and a second casing 220. The first casing 210 has adisplay screen 212 mounted on a front surface 210 a thereof, and thesecond casing 220 has an image-capturing apparatus 222. The first casing210 is a palm-size body that houses all major electronic components ofthe handheld electronic device 200 therein. Aside from the displayscreen 212, the front surface 210 a of the first casing 210 furtherincludes a matrix of telephone keys 214 and functional keys 216 betweenthe display screen 212 and the telephone keys 214. Furthermore, thesecond casing 220 is pivoted to a rear surface 210 b of the first casing210. When the image-capturing apparatus 222 is positioned in the rearsurface 210 b of the first casing 210, a lens 224 on the image-capturingapparatus 220 faces rearwards. At this position, images of objectsbehind the handheld electronic device 200 can be taken by theimage-capturing apparatus 222 through the lens 224 and displayed on thedisplay screen 212. If the user presses a predetermined one of thefunction keys 216 on the first casing 210, the image shown on thedisplay screen 212 can be stored in a memory of the handheld electronicdevice 200.

Referring to FIG. 3, the rear surface 210 b of the first casing 210comprises a hinge-accommodating groove 218 for receiving the secondcasing 220 therein. Furthermore, the hinge-accommodating groove 218 hasan opening 219 through an upper wall of the first casing 210. Since thehinge-accommodating groove 218 does not penetrate through to the frontsurface 210 a of the first casing 210, the handheld electronic device200 can have an integral and compact visual feeling. Furthermore, whenthe second casing 210 is received in the hinge-accommodating groove 218,a surface of the second casing 210 wherein the image-capturing apparatus222 is mounted flushes with the rear surface 210 b of the first casing210 to form a smooth profile for the handheld electronic device 200,whereby the handheld electronic device 200 is aesthetically appealing.As can be seen from FIG. 3, at this position, the hinge section 226 islocated between the display screen 212 and the image-capturing apparatus222.

The first casing 210 and thesecond casing 220 are joined together through a hinge section 226. Theimage-capturing apparatus 222 is set up at a position distant from thehinge section 226. When the second casing 220 flips up by 180° from theposition of FIG. 3 to the position of FIG. 4, the second casing 220extends through the upper opening 219, and the lens 224 of theimage-capturing apparatus 222 faces the same direction as the displayscreen 212. The second casing 220 can flip between first and secondpositions, wherein at the first position, the second casing 220 istotally received in the groove 218 as shown in FIG. 3, and at the secondposition, the second casing 220 extends through the upper opening 219 asshown in FIG. 4. Furthermore, after flipping 180 degrees, the lens 224of the image-capturing apparatus 222 now is located above the firstcasing 210 and faces a forward direction similar to the display screen212. Hence, the display screen 212 on the first casing 210 is able todisplay an image of the user of the handheld electronic device 200 whenhe (she) faces the lens 224. Thereafter, if the user presses thepredetermined one of the function keys 216 on the first casing 210, theimage of the user is stored in the memory of the handheld electronicdevice 200.

As shown in FIGS. 3 and 4, an extension plate 230 is formed at the upperwall of the first casing 210 and extends above the opening 219.Furthermore, the second casing 220 has a corresponding slot 232. Whenthe second casing 220 is flipped to the position above the opening 219,the extension plate 230 engages in the slot 232 so that theimage-capturing apparatus 222 is reliably fixed in position. Theextension plate 230 can also serve to cover a gap between the firstcasing 210 and the second casing 220 to improve the continuousness ofthe outer appearance of the handheld electronic device 200. Moreover,the outer surface of the second casing 220 is provided with serrations234 to facilitate the user's finger to manipulate the second casing 220to move from the first position to the second position and vice versa.When the image-capturing apparatus 222 faces a direction opposite to thedisplay screen 212, the image-capturing apparatus 222 is located belowthe hinge section 226. On the other hand, when the image-capturingapparatus 222 faces the same direction as the display screen 212, theimage-capturing apparatus 222 is located above the hinge section 226.

FIGS. 5 and 6 are side views showing a modification of the firstembodiment of the present invention, in which when the second casing 220is moved to the second position as shown in FIG. 6, the second casing220 tightly abuts against an edge of a top wall of the first casing 210so that a gap 240 between the first and second casings 210, 220 can beminimized to enhance the visual feeling of integrity of the handheldelectronic device 200. In this modified embodiment, in order to enablethe second casing 220 to move freely from the first position to thesecond position and vice versa, the hinge accommodating groove must beenlarged from the original position indicated by reference number 218 toa new position indicated by reference number 238.
